Which of the following is a strategy for malaria control?

Active surveillance is a critical strategy for malaria control as it involves proactively monitoring and identifying potential cases of malaria in a population. By using active surveillance, health authorities can detect outbreaks early and respond promptly, which is essential in preventing the spread of the disease. This approach includes rigorous data collection and analysis to track transmission patterns, identify high-risk areas, and target interventions effectively.

In contrast, while isolation of infected individuals can be a component of managing any infectious disease, it is not a specific control strategy for malaria. Mass vaccination programs are not currently a viable strategy for malaria, as there are no universally deployed vaccines for the general population. Finally, while mental health support is important for overall health, it does not directly contribute to malaria control efforts. Therefore, active surveillance stands out as a proactive measure that helps inform public health responses and control malaria effectively.
